same, reference being had to the accompany-` ing drawings, which form a part .of thisH specification. v

This invention relates to sanitary shaving cups and an object thereof is a cup in which a lather is formed for usein shaving that may be thoroughly cleansed after each use and the possibility of the transfer ofk disease germs accumulated by previous use thus avoided and thereby peculiarly adapt-ing the device for use in barber shops or wherever a single cup is used in shaving a number of persons. n

Another object is a device of the character stated in which the loss of soap from the cleansing operation is reduced to the minimum as the soap required in a single operation may be practically automatically supplied in the desired quantity, and a further object is in the provision of means for holding the shaving brush in such manner that thel bristles remain substantially in a straight line thereby preventing a distortion thereof ordinarily resulting from allowing lthe brush to rest in the bottom of the cup under which condition the bristles conform to the shape of the cup.

These and further objects and novelties of the invention are hereinafter more fully described and claimed and shown in the accompanyingdrawings in which- Figure l is a perspective view of a shaving cup embodying my invention. Fig. 2 is a vertical section thereof. Fig. 3 is an enlarged detail of a portion of the device more fully showing the valve controlling the passageway between the soap chamber and the lather chamber.

Similar characters refer tosimilar parts throughout the drawings and specification.

The cup may be formed of any desirable material, as metal, glass, or earthenware, and consists of a body portion l within which is formed a lather chamber 2 the walls of which are spaced from the outer specicatvionkof Letters ratent.' l Patgnted May 11, 1915u applicati/darned January 13,1913.A serialNo. 741,716.

wall of the body providing a chamber 3 therebetween for a liquid soap or other lather-producing solution. This chamber 3 preferably surrounds the lather chamber 2' andis provided with a lling opening normalflyclosed by'a screw 4 or similar device for the purpose. Also leading from the chamber to the chamber 2 is a passagewayV 5,. normally .closed bythe pivotally supported valve ,6 for'ywhich purpose. a spring 7 presses against'one end of a lever to which the valve is attached tending to maintain the valvel in .thel closed position. To this valve lever isalso attached a vertically positioned operating stem 8 passing through the'` upperwallfof the vsolution chamber and terminating in a conveniently positioned operating button 9. The stem 8 is also p rovided with a valve 10 normally closing the opening llA gthe chamber wall through which the stem passes and the spring 7, therefore acts inf` a `manner vto hold both Yvalves on the seats provided and the device lution to flow into the lather chamber, theV valve l0 is also depressed which allows air to flow into the solution chamber through the aperture in which the stem is positioned which allows the lather solution to How freely. t

Attached in any convenient manner, as to a portion of the handle of the cup as shown, is a brush supporting stirrup 12 preferably pivoted to the handle between the prongs of which the brush may be held when not in use and this support or stirrup may be turned on its pivot as shown by dotted lines in Fig. 2 so as not to project over the chamber 2 and the openingthereof is free of obstruction when in use.

The passageway 5 leading from the chamber 3 to the chamber 2 is preferably located near the lower end of the chambers in orderthat the solution may be as nearly completely emptied as possible by the natural {iow of the liquid when the valve 6 is open.

In operation the valve 6 is opened, as is also the valve 10, by depressing the button 9 whereupon any desired amount of solution in the chamber 3 may flow into the chamber 2 through' the passageway 5 and the valves then closed by the action of the spring 7 upon the release of the button 9. Hot water may then be added to the solution and the brush used to workthe solutioninto a lather and after the use of the lather in theusual manner in shaving the brush and brushV chamber 2 may be washed and thoroughly cleansed by any desirable antiseptic solution without the loss of lather solution other than what may remain in the lather or brush-chamber 2- as the valves are at this time closed. This operation is'repea'ted in the shaving of other individuals.'

From the foregoingdescription it becomes evident that the cup Yis inexpensive in construction, simple in operation havingr but few parts which parts do not readily become displaced and that all sanitary requirements in a device of thisnature are fully met, and

while'I have'shown avalVe operating stem of a peculiar nature, it isto be understood that various means may be employed for this purpose Without vdeparting from the spirit of this invention excepta's limitedby the appended claims.

Having and desire to secure by Letters Patent ofthe United States is- 1. In a shaving cup, open cupeshaped thus briefly described my invention and its mode'ot' operation, what I claiml lather chamber, a lather-producing solution chamber surrounding the lather chamber, said solution chamber being closed to atmosphere with the exception of a vent and a` closable opening and closed as to the lather chamber with the exception of a passageway therebetween, the latter chamber being supported at the top and bottom in the solutionchamber,said vent and said passageway being normally closed, and means for opening both the vent and the passageway.

2.y In a shaving cup, an open cup-shaped lather chamber, a lather-producing solution chamber :formed between the wall of the lather chamber and the outer wall of the cup, there being a passageway between said chambers near the bottom of the lather chamber, the solution chamber' being otherwise closed to atmosphere with the exception of a vent and a closable opening, a valve ynormally closing said passageway, a valve normally closing said vent, and means for operating said valves from the eXteriorof thecup.' Y

In testimony whereof, I sign this speciication in the presence of two witnesses.
